SAN FRANCISCO — A tsunami-producing fault in Lake Tahoe is overdue for another earthquake, scientists said here yesterday (Dec. 4) at the annual meeting of the American Geophysical Union.
The West Tahoe Fault is capable of producing a magnitude-7.3 earthquake and tsunamis up to 30 feet (10 meters) high in the clear blue lake, where million-dollar homes line the shore, researchers said.
Earthquakes strike every 3,000 to 4,000 years on the fault, and the most recent shaker was 4,500 years ago, indicating the fault is overdue for another earthquake, said Jillian Maloney, a graduate student at the Scripps Institution of Oceanography in San Diego.
